Yes like the red on the pic. Switch to + side of the coil and - to the distributor on a negative ground system. |

'Red' is right, for you... 'Blue' is bad, well it actually will work, but not as good a spark...... You will not damage anything if you miswire the coil. ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

if you connect it up backwards ( the BLUE photo).. you will have current flowing BACKWARD thru the point and condenser in addition to the coil... not an ideal situation. ------------- Like them all, but love the "B"s. |

| Distributer is the ground just like battery. If battery is pos. ground, coil is pos. grounded to distributer. MACK |

Christian, Don't forget, you have a Pertronix electronic ignition I fixed you up in that new Distributor so, from the E.I. in the Distributor, the RED wire goes to the plus (+) side of the coil, and the BLACK wire from the E.I. goes to the Negative (-) side of the Coil. The circuit from the Ignition switch goes to the plus (+) side of the coil with the RED wire from the E.I. I don't want to see you burn out your new E.I. The fellers here don't know you have an E.I.
